Spectrum Sharing between UAV-based Wireless Mesh Networks and Ground Networks
Zhiqing Wei, Zijun Guo, Zhiyong Feng +4
The unmanned aerial vehicle (UAV)-based wireless mesh networks can economically provide wireless services for the areas with disasters. However, the capacity of air-to-air communic…
Sensing-based Beamforming Design for Joint Performance Enhancement of RIS-Aided ISAC Systems
Xiaowei Qian, Xiaoling Hu, Chenxi Liu +2
Reconfigurable intelligent surface (RIS) has shown its great potential in facilitating device-based integrated sensing and communication (ISAC), where sensing and communication tas…
Magnitude Matters: Fixing SIGNSGD Through Magnitude-Aware Sparsification in the Presence of Data Heterogeneity
Richeng Jin, Xiaofan He, Caijun Zhong +3
Communication overhead has become one of the major bottlenecks in the distributed training of deep neural networks. To alleviate the concern, various gradient compression methods h…
Breaking the Communication-Privacy-Accuracy Tradeoff with -Differential Privacy
Richeng Jin, Zhonggen Su, Caijun Zhong +3
We consider a federated data analytics problem in which a server coordinates the collaborative data analysis of multiple users with privacy concerns and limited communication capab…
AMP-SBL Unfolding for Wideband MmWave Massive MIMO Channel Estimation
Jiabao Gao, Caijun Zhong, Geoffrey Ye Li
In wideband millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems, channel estimation is challenging due to the hybrid analog-digital architecture, which c…
